Ergodicity and Fourth-Order Spectral Moments

, 1997
International audienceRelationships between ergodicity and structures of fourthorder spectral moments are investigated. In particular it is shown that second-order ergodicity of a random process is directly related to the distribution of these moments on

Central Limit Theorem for Random “Contractive” Functions on Interval

Annales Mathematicae Silesianae
We use the approach from Czudek and Szarek (see [1]) to prove the central limit theorem for a stationary Markov chain generated by an iterative function system for a family of increasing, injective functions on [0, 1] with “contractive” properties.

Molecular Friction Trumps Viscosity in Angstrofluidic Transport

Small, Volume 22, Issue 51, 11 September 2026.
Single‐file transport through sub‐1 nm graphene nanopore and carbon nanotube is investigated using molecular dynamics and ergodic trajectory sampling. The study shows that confinement geometry and wall‐fluid interaction strength govern molecular mobility, allowing atomistic motion to be translated into a continuum‐based resistance coefficient for ...

Deep Learning for Protein Modeling: From Single Structure to Bound Complex and Thermodynamic Ensemble, With a Focus on Architectural Design

WIREs Computational Molecular Science, Volume 16, Issue 5, September/October 2026.
Protein deep learning is moving from single structure prediction toward bound complex modeling and conformational ensemble generation. An architectural perspective shows how symmetry, evolutionary information, generative sampling, and energetic grounding shape performance and generalization.

The Ensemble Kalman Inversion Race

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 9, September 2026.
Abstract Ensemble Kalman methods were initially developed to solve nonlinear data assimilation problems in oceanography but are now popular in applications far beyond their original use cases. Of particular interest is climate model calibration.

Knowledge as a Breaking of Ergodicity

Neural Computation
Abstract We construct a thermodynamic potential that can guide training of a generative model defined on a set of binary degrees of freedom. We argue that upon reduction in description, so as to make the generative model computationally manageable, the potential develops multiple minima.

Moment‐to‐Moment Dynamics of Foreign Language Enjoyment: An Idiodynamic Study of Conversational Topics Among Young Language Learners

European Journal of Education, Volume 61, Issue 3, September 2026.
ABSTRACT Foreign Language Enjoyment has received increasing attention in second language acquisition due to its role in fostering engagement and communication. Although previous research has often treated enjoyment as a relatively stable trait, perspectives informed by Complex Dynamic Systems Theory (CDST) suggest that emotions are dynamic, non‐ergodic,

Monetary and Macroprudential Policies under Dollar‐Denominated Foreign Debt

Journal of Money, Credit and Banking, Volume 58, Issue 6, Page 1693-1728, September 2026.
Abstract This paper studies monetary and macroprudential policies in a small open economy that borrows from abroad in foreign currency. The model features a novel mechanism in which exchange rate depreciation triggered by a borrowing constraint is amplified through balance of payments adjustments, increasing the real burden of foreign debt and causing ...

Strong Ergodicity in Nonhomogeneous Markov Systems with Chronological Order

Mathematics
In the present, we study the problem of strong ergodicity in nonhomogeneous Markov systems. In the first basic theorem, we relax the fundamental assumption present in all studies of asymptotic behavior.

Ergodicity and mixing in quantum dynamics

, 2016
After a brief historical review of ergodicity and mixing in dynamics, particularly in quantum dynamics, we introduce definitions of quantum ergodicity and mixing using the structure of the system's energy levels and spacings.
